Anybody able to reproduce that?
I installed dash in my chroot-testing and pointed /bin/sh to
/bin/dash, but couldn't cause him to fail. /bin/ash should be just a
symlink to /bin/dash and I don't know, if it behaves differently,
when called as /bin/dash.
I tested it only with tetex-bin_2.0.2-4.1 but I think that shouldn't
make much difference.
